PKA is composed of conserved catalytic subunits and regulatory subunits that dissociate upon activation by cAMP. The catalytic subunit of PKA contains the activation loop and mediates DNA binding and substrate recognition. The catalytic subunit is assembled and expressed as an active form and is phosphorylated on threonine 197 by PDK 1 in the activation loop and serine 338 in the carboxyl terminus. Phosphorylation of serine 338 plays a key role in stabilizing PKA and activating its substrates, and hence mediating its biological functions.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nForm-Liquid, Purification technique-Affinity purification Immunogen, Purification notes-The antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated PKA.

Mechanically it catalyzes the transfer of a phosphate group from ATP to a serine or threonine residue in target proteins impacting various cellular processes. This catalytic subunit has a molecular weight of approximately 40 kDa. It expresses widely in many tissues including the brain heart and skeletal muscle where it contributes to regulating metabolic and transcriptional activities.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThe PKA beta catalytic subunit functions in a larger context as part of the Protein Kinase A (PKA) complex which is a central player in the cyclic AMP (cAMP) signaling pathway. This complex acts as an effector of cAMP translating extracellular signals into intracellular actions by phosphorylating a wide range of target proteins. As a part of this complex it modulates activities related to glucose metabolism cell proliferation and gene expression reflecting its involvement in many cellular processes.\u003cbr\u003e\nPathways\u003cbr\u003e\nPKA beta is integrally involved in the cAMP signaling and insulin signaling pathways. In the cAMP pathway it activates by binding to cAMP leading to dissociation from regulatory subunits and subsequent activation of substrate proteins. In the insulin signaling pathway it interacts with proteins like PI3K and Akt playing an important role in regulating glucose homeostasis and lipid metabolism. These pathways illustrate the PKA beta's importance in maintaining cellular and systemic metabolic balance.\u003cbr\u003e\nThe dysfunction of PKA beta is associated with conditions such as cardiac hypertrophy and certain types of cancer. Elevations or disruptions in PKA beta activity can lead to alterations in cell growth and metabolic regulation. PKA beta's relationship with proteins like CREB and Bcl-2 through these disorders has been observed where aberrant phosphorylation mediated by PKA can drive pathological cell survival proliferation and growth linking malfunction directly to disease progression.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46848642613417,"sku":"ab5816","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab5816","provider":"Iright","version":"1.0","type":"link"}
